Re: [mpls-linux-devel] mpls-linux on 64 bit kernel

[Chris R. <Chr...@nr...>]

James, Jorge

Finally have a good (I think) Fedora 12 rpmbuild kernel as pings thru a 
LSP between LERs works.  However, netperf is failing with "Interrupted 
system call" on the netperf side (aka netperf --> netserver).  Below is 
the mpls debug ping and netperf output as seen from the netserver side).
I need to test using a file seed possible all the zeros is causing mpls 
some heart burn, I did test doing using FTP which of course ended up 
only using one LSP but it still worked.  I will do that later today 
using netperf seeded with a file.  Is there anything here you observe as 
strange?

One thing that does bother me is some debug output is missing, even with 
"echo "1" > /proc/sys/net/mpls/debug".  Possibly I'm missing something 
from "sysctl.log" settings?

Also, James, many moons ago I reported issues with 10GE running horribly 
slow.  At the time it was assumed when building MPLS-Linux, debug was 
turned off by default.  Ashan's discover suggested another look at the 
build files when of course I discovered its on by default.  So I will 
retest 10GE LSPs next week.  But might I suggest that debug be turned 
off by default?
